* See Bug 515 - https://jogamp.org/bugzilla/show_bug.cgi?id=515
*
* It is observed that ATI X11 drivers, eg.
*
* - fglrx 8.78.6,
* - fglrx 11.08/8.881 and
* - fglrx 11.11/8.911
*
* are quite sensitive to multiple Display connections.
*
*
* With the above drivers closing displays shall happen in the same order as
* they were opened, or shall not be closed at all!
* If closed, some driver related bug appears and brings down the JVM.
*
*
* You may test this, ie just reverse the destroy order below.
* See also native test: jogl/test-native/displayMultiple02.c
*
*
* Workaround is to not close them at all if driver vendor is ATI
* during operation.
*
*
* With ATI X11 drivers all connections must be closed at JVM shutdown,
* otherwise a SIGSEGV (after JVM safepoint) will be caused.
